ALBERT KELSEY, OF SVAMPSOOTT, MASSACHUSETTS.

SOLE-EDGE-SETTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 366,669, dated July 19, 1887.

Application liled December 2, 1886. Serial No. 210,441. (No model.)

To all whom, it may concern:

Be it known that I, ALBERT KnLsEY, of Swampscott, in the county of Essex, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Shoe- Sole-EdgeSetting Machines; and I do hereby declare the same to be describedin the following specification and represented in the accompanying drawings, of which- Figure 1 is a top view, Fig. 2 a front elevation, and Fig. 3 a longitudinal section,ofa ma chine embodying my invention, the nature of which is defined in the claims hereinafter presented. This section is taken to show the parts in front of the plane of section. Fig. 4 is a transverse section of it, taken through the setting-tool. Fig. 5 is a side view of the heel-post of the jack, showing the studs extending down from its base. Fig. 6 is a top view of the arm of the jack, showing its two ranges of holes. Fig. 7 is a back viewer elevation, and Fig. 8 an end view, of the mechanism for turning the jack. Fig. 9 is a front elevation of thesettingtool operative mechanism. Fig.10 is a side view of one of the abutments m hereinafter described, with its spring-tripper. Fig. ll is a top view, Fig. 12 a longitudinal section,(with its tubular bearing a,) Fig. 13 a side elevation, and Fig. 14 an end elevation, of the setting-tool, on anenlarged scale. Fig. 15 is an edge view of the gagep and guide 0, to which it is applied.

The machine, when having mechanism for reciprocating its jack carriage or slide, is antomatic, it, after a shoe may have been properly applied to thejaek, performing the operation of setting the entire edge of the sole of such shoe, except the heel part of such edge.

In the drawings, A denotes the frame for sustaining the principal operative parts of the machine. B is the jack for supporting a shoe, 0, while in the act of having the edge of its outer sole finished or set. The said jack is pivoted to a carriage or slide, D, so as to be capable of being revolved horizontally, the said carriage being adapted to the frame A, so as to be movable lengthwise and rectilinearly therein. The pivotal shaft or spindle of the jack is shown at a as arranged immediately under the post I), on which the shoe near its toe rests. The lower part of the jack is an arm, a, which, arranged horizontally, is slotted lengthwise to receive a projection, d, from a heel-post, e, such post resting on the top of the arm and being movable along such. From the base of the post two studs,'f, project and enter holes in two ranges of holes, 9, made in the arm and disposed lengthwise thereof, such studs and holes being for determining the distance of the heelpost from the toe post as the size of the last h may require.

The last, with the shoe 0 on it, is shown in position, such shoe and last being held in place on the heel and toe posts by a peculiar mechanism, which may be thus described: To the arm 0 there is a furcatcd yoke, 2', which is pivoted to the arm, so as to be capable of being turned from an upright down into a horizontal or nearly horizontal position. Each leg of the yoke i has a slot, 7., in its upper part. Through these slots a headed screwbolt, 1, extends horizontally, and has a nut, m, screwed upon it to hold it at any desirable altitude in the slots. A flat arm, a, pivoted at one end on the bolt, rests upon the heel of the shoe, and is furnished with a cushioned bearing, 0, to bear upon the sole. On the said arm, which is slotted lengthwise, there is an inclined plane, 1), that, adjustable longitudinally of the arm, is held to it by a clamp-screw and nut, (shown at (1,) the screw going through the slot in the arm. A cammed lever, r, shaped as shown, and fulcrumed to a projection, 5, extending from the yoke i, bears at its lower or cammed part on the top of the said inclined plane 1), and serves to depress the arm a and its hearing 0 upon the shoe, in order to secure the lat ter firmly within thejack. Springs '6', attached to the inclined plane and to the projection s, serve to raise the arm a while the longer arm of the lever 1- is being so depressed as to relieve the said arm from the pressure ofthe cam. The adjustable wedge or inclined plane by being movable lengthwise on the clampingarm, can be adjusted thereon as the size of a shoe may require to enable the cammed lever to work to advantage in pressing the clamping-arm downward for properly securing the shoe within thejack.

The carriage or slide D is provided with a toothed rack, a, for moving it rcctilinearly. Such rack engages with a pinion, '0, carried by a cross-shaft, 10, arranged as represented, and having on its front end a worm-gear, m, which in turn engages with a worm, 9 fixed on another shaft, 2, that by bevel-gears a and I) receives motion from adriving-shaft, 0, provided with pulleys d c, as shown.

On the pivotal shaft or spindle a of the jack there is fastened a pinion, f that engages with a rack, g, fixed horizontally to a slide or can riage, h. ported and movable lengthwise within an extension, 2', from the carriage D, and there is pivoted to the carriage it two hooked arms, k and Z, which extend from it in opposite directions, there being in advance of each of such arms a stationary post, m or in, having an opening, a or a, in it for the'arm to pass through, such posts being arranged as shown.

In theupper part of each post an orm there is a spring-presscr, 0 or 0", for depressing the arm, to cause it to hook upon the post at the proper time. Furthermore, there is pivoted to each post a short lever, 1) or p, that extends under the hooked arm, and is for forcing it upward out of engagement with the post, such lever at the proper-time being moved upward by a cam, q or q, extending upward from a slide, 0' or 1-". The two slides 1" 1" are adapted to an auxiliary slide or carriage, s, fixed to the carriage D, before mentioned, and movable rectilinearly and lengthwise of the machine by and with the said carriage or slide D.

The edge-setting tool t is arranged within, and so pivoted to a furcated carrier, 1, as to be capable of turning horizontally or laterally therein, such carrier being journaled in a tubular bearing, a, projecting from a slide,'o, adapted to play vertically within another carriage, w, that is adapted to slide horizontally in a third carriage, w, supported by ways, so as to be movable transversely of the machine and rectilinearly toward and from the shoe. The end of the journal of the carrier t rests against a spring, i in the bearing a, and the said carrier is so held in connection with the said bearing by a screw, a, and a notch o, in the shank of the carrier, as to admit of its moving endwise'against the spring, and also of turning axially sufficiently to allow the setting-tool to accommodateitself to the upward and downward curves in the edge of the sole. To such carriage :0 there is fastened a rope, 1, that goes over a guide-pulley, z, and thence to and is fastened to a lever, a, arranged as represented. From this lever a rod, b extends upward through the top of the frame A, such rod being to receive one or more weights, 0', to aid in moving the carriagewforward,in order to keep the setting-tool with a suitable pressure against the sole-edge. To the upper part of the slide 12 a rope or cord, (1 is fastened, such rope beingled over and in grooved guide-pulleys 0 supported in a standard, f

The rope has a weight, fixed to it, such rope and weight serving to lift the carrier t upward, as occasion may require, to cause the edge-setting tool to conform to the sole-edge. Furthermore, the carriage 20 has mechanism for reciprocating it horizontally, such mech- The said slide or carriage 71 is supanism consisting of a connectingrod, h pivoted to the carriage and to a crank, i on the end of a. shaft, k such shaft being arranged as shown and provided with'pulleys Z, W, a, for revolving it by a beltfroma prime motor.

There is applied to the front of one of the stationary vertical and parallel guides o of the slide 12' an adjustable gage, p to limit, with a screw, (1 screwed into the slide 22, the extent of upward movement of such slide, in order to bring the edge setting tool to its proper altitude to engage with the shoe-sole. This gage is slotted vertically, and is confined to the guide o by a setscrcw, 1 (see Figs. 9 and 15,) going through the slot 8 and screwed into the guide.

The slide D is furnished with two piers, 10 to support the jack-arm a when in either of its extreme posit-ions. Between the said piers there is extended up from the slide two abutments, w 00 against one of which a spring, 1, fixed to the arm, butts or brings up, in order to hold'the jack stationary in one of its extreme positions, such spring in like manner bringing up against the other abutment when the jack is in the other extreme position. There is pivoted to each abutment an arm or tripper, z or a, that extends transversely under the said spring, and there are fixed on one of the guideways a of the slide D two adjustable cams, I) c", which, as the tripper a or 2 by the slide D is 'carried lengthwise over and upon either of such cams, will be forced upward, so as to press the spring high enough above the abutment forthe jacks to be revolved in proper time, and without obstruc tion from such abutment and spring.

In order to hold the edge setting tool back out of contact with the shoe when necessary, there is extended up from the carriage or slide at a knob, d, and in advance of such there is a levereatch, c, which, fulcrumed to the slide m, is to operate or engage with a toothed rack, f, fixed on one of the guideways of such slid 00, all being as represented. 1

For heating the edgesetting tool there is arranged under it a gas-burner, 5 provided with a fiexile pipe or hose, h", for conducting combustible gas ,to such burner as occasion may require.

The flat arm a of the jack, slotted lengthwise, as hereinbefore stated, has applied to it a block, 9, having spurs or points extending down from it. This block is connected with the arm by a set-screw, h, which goes down through the slot in the armand screws into the block.

from its outer sole, the bloekunder such circumstances being moved directly over the heel portion of the outer sole, which, when the arm Such block is to be used when a, shoe to be operated on has no heel projecting n is forced down by the cammed lever 1', will be held down firmly upon the last by the said block.

The setting-tool is slotted down its front face inwardly, as shown at a in the drawings, the slot causing it not only to turn or vibrate to advantage against the sole-edge, but to remove the surplus blacking or coloring-matter from such edge while the tool may be in action thereon.

The operation of setting the edge of a boot or shoe sole by the hereinbefore-described machine may be thus described: A shoe or boot having been applied to a last and clamped to the jack, as shown in Figs. 1, 2, and 3 of the drawings, and motion being imparted to the shaft 7; by a belt running from a suitable mo tor around one of its pulleys, a short rapid reciprocating movement will be given to" the settingtool t by means of the crank conneetingrod 71?, and slide to. The carriage as is next to be advanced toward the shoe by the hand of the attendant applied to the knob d, and the carriage D is to be in a position to admit of the tool commencing at the front end of the heel to set the edge of the sole. (See Fig. 1.) The shaft 0 is next to be set in motion by power applied to one of its pulleys by means of a belt from a driving-pulley, and the.ear riage D will be moved to the right by means of the gears b a, shaft a, worm g, worm-gear x, shaft to, pinion v, and rack a. As the carriage Dadvances, the hooked arm Z will enter the opening 91/ in its post an, and will elevate its presser o", and as soon as its hook has passed through the said opening the presscr will force the hook down below the bottom of said opening. \Vhen this takes place, the hook of the arm will reach its post at, and, as the carriage D still continues to move in the same direction, the hook of the arm 7.: will hold the carriage h and its rack g from moving. \Vhile this movement of the carriage D and the parts carried by it has been going on, the tripper of the abutment 4r (against which abutment the spring 1 has borne and has held the jack from turning on its axis against the pressure of the setting-tool) has been raised by the cam c, and the spring 1 set free from the abutment x at the time when the hook of the arm it" reached its post m. The pinion f will now, on account of the continued movement of the carriage D, be caused by the rack to turn the jack B on its axis. During the turning movement of thejack the toe of the sole will be set, and when the jack shall have turned one hundredand eighty degrees of a circle, or thereabout, the spring f will catch on the other abutment, .rfland the other edge of the sole will now be in the proper position to be operated upon by the settingtool. \Vhile the jack has been turning on its axis, the carriage D has been still moving to the right, and has carried the cam q of the slide 1" under and against the lever p and caused it to raise the hook of the arm k sufficiently to release it from its post and allow it to pass through the opening a, and from under its presser o during the furthermovement of the carriage D to the right, which movement ceases when the setting-tool reaches the front end of the heel on the opposite edge of the solo from which it started.

In practice I apply to the rack a mechanism that will so operate the shipper of the driving-belt of the shaft 0 as to cause the movement of the carriage D to cease at the moment the setting of the edge of the sole has been completed.

The setting of the edge ofthe boot-solehaving been finished, as described, it, with its last, is to be removed from the jack, and its mate, with its last, substituted, the edge of the sole of which will be set in precisely the same manner as hereinbefore described, during the return movement of the carriage D.

Having thus described my said machine for setting the edge of the sole of ashoe, Iclaim- 1. The combination of the furcated yoke i, the arm n, adjustable on and pivoted to such yoke, as described, the inclined plane 1), arranged and adjustable on the arm, as explained, and the cammed lever r, pivoted to a projection, s, from the said yoke, such yoke being pivoted to the arm of the jack, and all being to operate substantially as set forth.
